What is an RF engineer contract?

An RF Engineer contract position involves working on projects related to radio frequency (RF) technology, usually for a specified period or project duration, rather than as a permanent employee. Contract RF Engineers design, analyze, and optimize systems such as wireless communications, antennas, and RF circuits. They may be hired by telecommunications companies, defense contractors, or engineering firms to address specific technical needs or workloads. This role often requires specialized knowledge of RF principles, testing equipment, and relevant industry standards.

What are the key skills and qualifications needed to thrive as an RF engineer contractor?

To thrive as an RF Engineer Contractor, you need a solid background in radio frequency theory, wireless communications, and relevant engineering degrees such as electrical or telecommunications engineering. Familiarity with RF design tools (like Ansys HFSS, CST, or Keysight ADS), spectrum analyzers, and relevant certifications (e.g., FCC or Cisco wireless certifications) are typically required. Strong problem-solving skills, attention to detail, and effective communication help you excel in cross-functional teams and dynamic project environments. These skills are vital to ensure reliable network performance, minimize signal interference, and deliver quality solutions to clients on time.

What are the most common challenges RF engineers face when working on contract assignments, and how can they be managed?

Contract RF Engineers often encounter challenges such as rapidly adapting to new team dynamics, quickly understanding project requirements, and integrating with unfamiliar tools or systems. Since contracts are typically project-based and time-limited, there can be pressure to deliver results quickly while maintaining high technical standards. Effective communication, proactive learning, and leveraging prior experience in similar environments can help contract RF Engineers overcome these challenges and make a positive impact from day one.

What is the difference between Rf Engineer Contract vs Rf Engineer Full-Time?

Employment TypeTemporary or project-basedPermanent
Work EnvironmentContract roles often in multiple companies or projectsIn-house or dedicated team
Certifications & CredentialsTypically the same; requires RF engineering skills and certificationsSame as contract roles
Job StabilityLess stable, duration depends on projectMore stable, ongoing employment

In summary, Rf Engineer Contract roles are temporary, project-based positions offering flexibility, while Rf Engineer Full-Time roles provide long-term stability within a company. Both require similar skills and certifications, but differ mainly in employment duration and work environment.

Job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are looking to add a Principal RF Test Engineer I to our team. If you enjoy working in a startup environment and are passionate about developing critical test systems for leading-edge satellite, spacecraft, and aerospace communication systems, we would like to hear from you.
 
In this position, you are responsible for the design, analysis, and implementation of engineering test plans and procedures. The ideal candidate possesses a strong combination of hardware and software knowledge with proficiencies in RF measurements, test equipment (VSAs, VSGs, VNAs, etc.), test architectures, and automation. The successful candidate will work closely with multi-disciplinary teams to address company-wide hardware test needs. Experience with phased array testing is preferred.
 
Core day-to-day responsibilities include collaborating with design and test engineering teams to develop test requirements, mapping requirements to reusable test architectures and procedures, implementing test plans and procedures, and logging and presenting results to key stakeholders. Additional responsibilities include lab and equipment management and guiding key equipment purchase decisions.
 
Principal-level test engineers are distinguished by an ability to architect RF test systems, to draw insightful conclusions from test results, and to participate in “design for test” planning and review from the early stages of RF product development. Test engineers are core members of the Cesium technical team.
 
The successful candidate will present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • Bachelor of Science (BS) or higher degree in Electrical Engineering or Computer Engineering from an accredited university or institution.
  • Minimum of 9 years of industry or university research experience in design, analysis, and implementation of RF test systems. 
  • High proficiency with RF measurements (Linearity, NSD, EVM, etc.).
  • Test architecture design and development including scripting, test executives, hardware, and measurement abstraction layers.
  • Proficient in performing conducted RF measurements including S-parameters, AM/PM, compression, noise figure, harmonics/spurious emission, phase noise, switching speed, bit error rate, adjacent channel power, and group delay.
  • Hands-on experience with lab instruments such as digital oscilloscopes, multimeters, electronic loads, source measurement units, RF signal generators, spectrum analyzers, network analyzers, and vector signal analyzers.
  • Excellent written and verbal communication skills.
PREFERRED EXPERIENCE
  • Familiarity or hands-on experience with phased array over the air range testing, including phase/amplitude calibration, EIRP, G/T, axial ratio, scan loss and pattern cuts.
  • Programming or scripting experience (Python, MATLAB, C/C++, etc.)
  • Understanding of RF and mixed-signal hardware (e.g. amplifiers, filters, ADCs/DACs, antennas) and its effects on test design.
